Monitoring systems for large hydrogenerators
Yacyret is the largest hydroelectric power plant, at present under construction, in the world: it is located on an island on the Rio Paran, in Paraguay, near the Argentina border. The power plant has twenty 172.5 MVA, 84-pole hydrogenerators (units 1-10 supplied by Mitsubishi, units 11-20 manufactured by Siemens and Ansaldo). The last ten are equipped with a special monitoring system supplied by Ansaldo. The MONTRA system makes possible on-line control of the air-gap, by means of 8 special sensors, Air Gap Monitoring System (AGMS) commercialized by VibroSystem (Canada); installation and commissioning of the system were by Ansaldo. On the same ten units a system for on-line monitoring and analysis of partial discharges (commercially named SCAPAR) developed by Ansaldo is provided too. At present the tenth unit is under commissioning and all the ten eventual units supplied by Siemens and Ansaldo will be equipped with the above mentioned monitoring system
